  • Prove that the number 251 is prime. - analyze the number 2008 into prime factors , and deduced the natural numbers whose Cube divides each 2008. - Find the natural numbers a and b such that: m3 + 35d3 = 2008, note that :
    d = PGCD ( a ; b ) and m = PPCM ( a ; b )

if a number cant be divided by the prime numbers smaller than the square root of it, then the number is prime

#

251 cant be divided by 2, 3, 5, 7, 11, 13 which is smaller than √(251)≒15.xx

#

so 251 is prime

#

2008 = 2^3 × 251 so the numbers would be 1 and 2

#

a=2, b=6
